Wastewater Pretreatment

Industrial Pretreatment Program

The Industrial Pretreatment Program helps protect Collier County’s wastewater treatment facilities by making sure businesses follow proper wastewater rules. These rules meet the requirements of the Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (FDEP).

We partner with local businesses in reducing pollution before it enters the sewer system to protect public health, maintain our infrastructure and reduce long‑term costs. The program helps to:

• Keep harmful pollutants out of the wastewater system
• Prevent pollutants from passing through treatment without being removed
• Support recycling and reuse of wastewater and sludge

Program Oversight and Requirements

Collier County’s pretreatment program is authorized by FDEP and Chapter 134, Article IX of the Collier County Code of Ordinances. The program includes:

Industrial Discharge User Permits

Many industrial facilities that discharge to the sewer system are required to have an Industrial Discharge User Permit.

Many industrial facilities require an Industrial Discharge User Permit to send wastewater into the county sewer system. These permits typically require:

• Regular testing of wastewater
• Routine reporting of results
• Compliance with local, state, and federal standards

To ensure accuracy and compliance, the program also conducts its own monitoring and inspects each permitted facility at least once a year.

Fees and Additional Information

Facilities pay a monthly fee, which is included in their water and sewer bill. Inspection and related program fees are listed in the Collier County Fee Schedule.

Regulated establishments must maintain written records of the maintenance activities for all grease removal devices. These records must be retained for a period of three years and available to county inspectors during an inspection. These records must include:

• Time and date of maintenance or cleaning.
• Name(s) of the individual or company that performed the maintenance.
• Details of any repairs required and dates of repair completion.
• Name of approved hauler.
• Volume hauled.
• Type of approved additives.
• Copies of either the licensed hauler's receipt or manifest.
• Any other relevant records.
